Outside kindergarten activities are designed as planned and structured activities that are extremely important for children's self-realization. The aim of this thesis is to investigate whether there is a difference in the motor skills of children who engage in physical activity only during educational work and children who are included in an additional sports program after kindergarten, universal small sports school. For the purposes of this work, 37 children participated, of which 19 were boys, who are included in a regular ten-hour program in a preschool institution and have scheduled time for conducting physical activities once a week for one hour in the hall. The children are aged 5,5-6,5 years. Another group of children are beneficiaries of the small sports school program, which takes place three times a week for one hour. The children with whom the tests were conducted were included in this program for one year. Trainings are conducted on open sports fields. The program is aimed at developing and expanding the repertoire of motor skills through different natural forms of movement with an emphasis on proper performance. Research has shown that children using the sports program are better in all tests of motor skills, especially tests of endurance and coordination. The hypothesis that there is a difference in the motor achievements of children, that children who use the additional program have better motor skills and a lower body mass index, was confirmed.
